The odds of Matt Kemp playing in this year's All-Star Game are getting slimmer by the day.

Dodgers manager Don Mattingly said Monday the organization has decided the National League's leading vote-getter won't play in the July 10 Midsummer Classic in Kansas City until he's at least logged some playing time.

He said Kemp, on the disabled list for the second time with a left hamstring injury that's dogged him most of the season, would have to play about five or six games on a minor-league rehab assignment before coming to the Dodgers. The scenario of all that happening within two weeks is growing increasingly unlikely.

"It's a long shot at this point because he's not healthy," Dodgers general manager Ned Colletti said, summing up Kemp's All-Star status outlook.
